Biography
Shams ud-Din was from the Sunni Muslim Kartids, a dynasty of Turks that ruled Khorasan as vassal princes under the Mongol Empire from 1244 onwards. Shams ud-Din succeeded his father Rukn-uddin Kurt I on his death in 1245, and Shams ud-Din subdued Herat immediately, before he submitted to the Ilkhanate. In 1247 he took part in a Mongol invasion of India, and he visited the newly-crowned Mongke Khan in Mongolia in 1251. Shams ud-Din later converted to Orthodox Christianity at Hulegu Khan's request during his Christianization of the Ilkhanate.
